Display Uniformity

For these tests, the screen is divided into nine areas and measurements are taken for each. The first set of results is about colour uniformity, i.e. how consistent colour output is across the various areas of a screen. It is measured in delta E values, and the lower the value the less variation there is and the better a screen is considered.

The second set of results is for luminance uniformity i.e. how well brightness levels are maintained across the various areas of a screen. The results are reported as a percentage that indicates how far a certain area is from the brightest recorded area. Again, we are looking for values as low as possible to signify the best consistency.
